CPU fan error

My CPU fan failed. I replaced it with a new fan. The is working fine. However, I get the CPU fan error message on booting. After pressing F2 key, the PC boots and is working fine for prolonged hours. While I tried to determine the cause of the error message from the BIOS, I found that there is nothing to select in the Advance tab. I want to know why this error message appears every time I boot the machine and how to resolve it.

The replacement fan should equal the "rpm" of the former fan. If it's slower, you will be this warning. If its too slow,  the computer will shutdown.

  • HP P6203W CPU fan error on startup windows 7 32bit system

    Hi there guys !
    I got this HP computer for about a year now and since changing my broken CPU fan i got a CPU fan error on startup. 
    I have got a HP P6203W
    MOBO: Pegatron Narra5
    Bios: phoenix technologies 5.55 12/08/2009
    I wanted to reduce some noise from my computer by replacing the CPU fan,
    so i changed the original fan for a Noiseblocker-Multiframe M8-S1.
    Now when i start up the computer; the fan slowly turns around , and i then got an CPU fan error before windows fired up. I can get past it by pressing F2 but its annoying to do so every time i start up. Plus I don't think the fan is turning fast enough.
    I already tried checking cpu fan settings in the bios, but i have the blocked bios.
    No fan settings here.
    Do one of you guys have any clue about how to get my CPU fan working properly again or maybe a bios update for my motherboard ?
    Any help would be very much appreciated !
    thanks for your time

    Hello willibrord87,
    There isn't a BIOS update available for your motherboard so that is not going to be an option.
    On some BIOS you have the ability to disable the system from checking the CPU Fan to avoid the error. If it's there it would be under Advanced menu and then a sub menu called Hardware Monitor. HP like many manufacturers lock out settings to avoid users changing settings to much in the BIOS so the system may not have the option. Since you said you already checked the settings I'm assuming we can skip this.
    So it brings us to the motherboard. The CPU fan plug on the motherboard is a 12v connector, the Noiseblocker you have starts a slow ramp up based on this link http://goo.gl/6jsgn it says it's a start voltage of only 5v. I'm thinking that since the CPU fan is not starting up quick enough the motherboard is failing out and giving the CPU fan error. In the end the error is not a real error because once the CPU fan actually works then it's good to go.
    You may want to try a different CPU fan that has a quicker spin up, or at least move that CPU fan to another system to see if it exhibits the same slow spin up.

  • Asus p5k cpu fan error

    I finally installed my new cpu cooler today ( Noctua NH-U9B SE2 ) and went from my old vacuum cleaner fan at 80°C to an ultra quiet 25°C. But when booting up, i get a damn cpu fan error for whatever reason, and i get a few beeps and have to press F1 to continue. Why is that? I connected my new fan to the 3-pin and not the 4-pin, is that the issue? i could try the 4-pin ( the connector head only have 3 holes though ) but i wouldn't wanna risk making my mobo fubar. How do i fix it?

    I had the same problem on my ASUS/HP IPIBL-LA motherboard, error 9998. I solved in this way:
    1) The Brand BIOS is American Megatrends, so i downloaded their utility AMIBIOS flash utility from here http://www.ami.com/Support/amibiossupport/
    2) Then use winrar or a similar program to get only the file 513.ROM from the file sp37377 (that is the BIOS).
    3) open the folder amiflash, then AMIBIOS, then AFUwin, select the folder 32 or 64 (depends on your operating system), run the application
    4) Click on 'OPEN' in the bottom of the window and select the file '513.ROM'
    5) go in setup-CMOS options and select 'Load ROM file's optimal', select also 'restart after programming'
    6) close all the running applications and click 'FLASH'
    after the restart you have to go in the Bios pressing F10, set the bootable Hard disk, save and restart.

  • System fan error on g62-352ca on startup. are there two fans ie a cpu fan and a system fan?

    I get a system fan error on power up?     Are there two fans in the G52-352CA?   Ie a general system fan and a CPU cooling fan or just the one CPU/heatsink fan?
    If it is the CPU/heatsink fan then there are 4 part numbers for different options.   Is there some way to tell from the model number or features as to which is needed.    I would prefer to have the part in hand before opening everything up.    Are there better fans to buy and if so how do I find them?       This unit was always running a little on the warm/hot side,

    I suspect you have hardware problem with a fan sensor. Doing a software install will not help the machine needs to be taken in for service. If you run Apple Hardware Test in Extended Mode it should reveal the error code. If it does not then run AHT an additional 2-3 times to be sure in Extended Mode. Each pass will take about 30-60 minutes.

  • T61-Fan Error on startup and cant boot in system

    after Thinkpad logo, 2 short 'Bee' sound and 'fan error' message appears on the top left screen, then 1 'Bee' sound, laptop shut down. Althought can boot in system by pressing Esc when 'fan error' appears, but dont know this will damage something like circus or chips.
    Anyone have same problem and solved it? Should I change the fan, and which fan (video car fan or cpu fan) is this problem about. I have a limited warranty dont know if the fan is included.
    Thanks

    Fan is covered by warranty, when fan stops spinning then it would usually cause this error.

  • Dc5850 cpu fan speeds to top speed sys then shutdown

    I have a Hewlett-Packard HP Compaq dc5850 Micro tower PC, now running windows 7 pro 64-bit. That was new in late 2008. Originally it came with vista 32-bit downgrade able to XP pro 32 bit, running on 2G RAM, and 160G C drive with a 2.30 gigahertz AMD Phenom 8600B Triple-Core processor. It also has ATI 3100 integrated graphics as well as integrated NIC at 1G and integrated High def audio. In the first few months I had the system, I upgraded memory by 4G and total Disc space by 500G by adding a D drive; then upgraded to windows 7 pro 64-bit.
    Overall, I have had a good experience with the PC but it has had problems while in its 3-year warranty. I did need to replace the C drive and later it original RAM devices. Yes HP did these replacements and swaps, under warranty; that meant I had 6G memory for a long time before the HP 2Gig failed out of warranty, leaving me with 4Gig now. Yes I have always had the Unit on an UPS; I even replaced the old UPS with a more powerful unit in late 2009 or early 2010 when the old UPS showed signs of failure. Now instead of serial based UPS connection it is USB.
    Over the last few months I have been getting blue-screen errors of all sorts. Ranging from video related errors, Memory faults, Disc read/write failures and processor flag errors too. After numerous repair disc runs or re-install of windows, the disc read write errors wore corrected by the HP drive sanitation utility disc repair/wipe after failing the extended test. The non video ram was tested by a bootable CD of memtest86 v4 running extended test as well as MS memory Diagnostic. Both run multiple times, both passed multiple times. I was able to find a CD based video diagnostic for ATI and the Video passed repeated stress test as well. Over Labor Day I conducted these test and re-installed windows 64-bit; on the following Monday windows informed me I needed to activate windows, so I verified the correct key and called to do so, successfully.
    With that background given here is the question. Recently over the last two or three months, for no apparent reason, mainly on boot the fan races to top speed and the system shuts down to protect itself. I researched this a little and found one cause to be inadequate airflow over the CPU to keep it cool; the recommendation made sense to vacuum with a computer vacuum and be sure airflow is not somehow obstructed. I am now thinking all these problems are related to the CPU temp sensor. Is it on the CPU fan or the motherboard, and can raising the fan speed in BIOS help prevent the problem, particularly if it on the motherboard.
    John M Gray II

    My pentium 4 3.0c stock Intel fan is 4.44 watts. Isn't the mobo designed for this?
    Also, can the sys fan header have the speed sensor activated by a bios fix or is it a hardware issue where it just does not exist? If hardware, seems strange since Corecell shows sys fan.

  • Dual CPU fans in IQ816 Question

    I have received the fatal error message indicating that my wife's IQ816 CPU fan is dead. 
    When I opened up the unit I found that one of the 2 CPU fans was indeed not functioning (FYI there are a total of 3 fans in the IQ816s). The fans part number (on the part) is 13G075205000H2 which translates to HP part number 489487-001, and I have ordered a couple of these already.
    However, the second CPU fan (located right next to the other one) has part number 13G075205030H2 and I have not been able to find this part number anywhere (it is the same as the first part number with one of the 0s changed to a 3 so it is possible that the same part number may be okay with both, but I have no way of knowing that).
    Could someone please let me know what the HP part number is for the 13G075205030H2 as I know this fan will die eventually, and I would like to be prepared with the replacement part in hand.
    Thanks in advance,
    Don McFarland

    For those who may read this thread who are not familiar with PC hardware issues, there are some basic parts which can go bad and cause a machine to no longer function. Historically, manufacturers produce these parts so that customers who need them can keep their machine up and running rather than having to buy a new one. These parts include...
    (1) CPU - okay, chances are good that the CPU manufacturer will take care of this being available
    (2) CPU Fan - on newer machines, the BIOS will not allow the machine to boot if a CPU fan is not working - whether or not these are available is largely up to the part that was selected by HP - there is no guaruntee that the part will be available unless HP makes that happen.
    (3) Memory - okay, chances are good that a memory manufacturer will take care of this being available
    (4) Hard Drive - there are plenty of hard drives out there to choose from
    Note that of these 4 items, HP is off the hook on 3 of them due to the stock that other vendors maintain, namely the CPU, Memory and Hard drive. The least expensive (by a longshot) critical part is the CPU Fan/heat-sink (production cost is a few dollars).  One has to ask oneself, why HP would not make these parts available, because without them, a $2000+ computer (IQ-816 for example when they first came out) becomes a worthless piece of &^%^.
    I am really having a hard time believing this sad state of affairs. For anyone reading this, make note that it does not matter how much you paid for your high end HP computer when it comes time for replacement parts, because HP is not taking the responsibility that they should to look after their customers - it may run for a couple of years or so, but when the trouble hits, you may find yourself in the same situation that I am in (i.e. can't get a part that is necessary for the computer to run).

  • CPU fan spins up for no reason and never spins down

    I'm having problems with my new and otherwise immaculate iMac Intel 2.4 GHz. The CPU fan often spins up to 3500 rpm for no reason, even when left idle.
    There are no processes running to justify the noise (no Spotlight indexing or anything) and the temperatures are as low as can be.
    I have tried resetting PRAM and SMC many times to no avail.
    Usually putting the Mac to sleep and waking it up slows the CPU fan down again, but it will go nuts at 3500 rpms sooner or later.
    Once the fan has spun up to 3500 rpm it never spins down again unless the iMac is reset or put to sleep and woken up again. Even when hours of useless fan spinning has left it freezing cold.
    SMCFancontrol won't help as it can't slow down fans only make them go faster.
    Apple Support suggested I'd take it in for repairs but I'm reluctant as this smells like a Leopard/Boot Camp Issue from what I gathered on the boards. Also the repair service in Denmark is outsourced to third party repairers of questionable quality.
    Any ideas?

    I got my iMac back from repairs. They said they couldn't reproducere the error which might be as it at times appear very sporadic. The fans began to spin within the first day of use after I got it home though.
    It seems that more and more users on the boards experience this problem. My theory now is that this must be a software issue as it usually begins once people update to Leopard 10.5.2.
    The problem manifests itself like this:
    The CPU-fan will start blowing at 3500 rpms for no reason (CPU-load and temperatures can be as low as can be.)
    The CPU-fan will never slow down again by itself. Even after hours of unnecessesary spinning has left the Mac freezing cold.
    Putting the iMac in sleep mode and waking it up again will temporarily slow down the CPU fan down to the usual 1200 rpms (usually for about 10 mins).
    Resetting PRAM and/or NVRAM (SMC) will not help.
    Installing SMCFancontrol will not help as it will only let you speed up the fans further - not slow them down.
    So now I really hope Apple will address this problem with a new OS X release soon.
    Still, if anyone manages to fix this problem with a hardware replacemnt please let us know.
    Cheers, Jez

  • IMac cpu fan running at full rpm

    hi all
    A few days ago my cpu fan started running flat out. I have done the smc or whatever it is caled reset thing where you unplug the cored ect.
    I have done the hardware test with no bad results.
    I have checked activity monitor for cpu usage and there is nothing unusual there, so I can only guess that the cpu temp censor is faulty.
    I should also add that this machine has been running non stop since mid 2007 , with the exception of the odd blackout and restart, thats pretty amazing i think.
    maybe its time has finally come ;(
    any clues ??
    thanks

    SMC is firmware and OS X is software, which has nothing to do. Furthermore, you are using a very old iMac, so SMC should not have been updated with OS X 10.10.2.
    If you have tried a SMC reset and it did not work, run Apple Hardware Test (make sure you choose an extended test) to see if there is any problem with a temperature sensor or anything like this -> Using Apple Hardware Test - Apple Support
    Note that you may need the DVDs that came with your Mac in order to run it. If you get an error at the end of the test, please copy it here.

  • Cpu fan 90B alarm and plugged in but not chragiung alarm

    hi,
    I have HP notebook product: b6u29pa#acj and model: g6-2101TX.
    I am getting following problem:
    A. while start up pc i found alarm 930B cpu fan failure and then after restarting window7 start.
    B. many time when i put laptop for changing it shown plugging but not charging and led near to charging port keep on biking white colour. that time charging not happen so if i removed charger and keep on using notebook my battery level is not getting down and suddenly at one point notebook power off. That means battery getting used but notebook not getting understand and giving me battery low alarm. Then i have to remove battery and insert it again. it will work for 2-3 days n then same problem repeat.
    ( pl note that note book battery is good and giving 2-3 hours backup when fully charge)
    Both my problem was chronic so i took photograph when problem came and then given laptop for repair at service centre as it was under warranty.
    Then next day i received call from service centre that my laptop ok pl come and collect. so i went to service centre when i checked found same problem so they took back and said motherboard is faulty.
     for CPU 930B fan alarm they only clean fan may be alarm will come in few days.
    after 8 days yesterday i received  call again from service centre that my laptop is ok.
    now my question is if my laptop is not ok then what to do? as my warranty was exp. on 23.08.2014 ( i need few days for trial ) may be after replacing motherboard any other problem appear. Will HP give few days for trials?
    or any government intervention is required ?

    Hello @yoursviru ,
    Welcome to the HP Forums!
    I understand you have issues with charging and a 90b fan error on startup.
    To address your question about a trial period after repair: Typically the repairs should include a 90 day service warranty or the remainder of your existing warranty whichever is greater. This depends if the repair was done by HP or an authorized HP provider. HP Phone Support can confirm this for you.
    If the repair was not done by HP or an HP service provider HP cannot guarantee the work of third party companies.
    The power not charging the notebook could be an issue with the battery, internal power connector cable, power adapter, or motherboard. All of which are hardware related.
    You can read about the fan error here and what to do to fix it: System Fan (90b) error message on startup.
    To sum everything up. I suggest you get in touch with HP Phone Support as soon as possible as they are the ones who can give you a straight answer regarding service and warranty questions. My answers are based on personal experiences, as the forums do not offer service and are available regardless of the warranty status.
    Hopefully Phone Support can give you the answers you're looking for.

  • ACK Issues! Long Bootup and roaring CPU fan!!

    Hi all,
    Two issues...
    My 2 yr old iMac takes anywhere from 3-8 minutes to bootup. I get this grey screen with a circle and line through it. Then it boots to the normal desktop. LONG time..?
    Secondly, the CPU fan roars all the time. It's pretty loud. I've used compressed air on the vent in back, but to no avail.
    I'm running Tiger, 10.4.11. iLife 09
    I'm wondering if I should upgrade to Leopard or Snow Leopard.... Would this help? Can I upgrade straight to Snow Leopard? Or do I need to go step by step through Leopard then Snow? LAME if I do..
    Any other suggestions?
    Thank you SO much!!
    Jay.

    Hi Jay,
    I get this grey screen with a circle and line through it. Then it boots to the normal desktop.
    Most likely Hard Disk problems.
    Have you booted off the Install Disk by holding the *d key* down at boot-up, (not the c key), and run the extended Apple HW Test? Some Install disks require holding the Option key at bootup to select the AHT. Some Macs came with separate AHT CDs.
    Secondly, the CPU fan roars all the time.

    I'm wondering if I should upgrade to Leopard or Snow Leopard.
    I wouldn't just yet.
    Any other suggestions?
    http://www.bresink.de/osx/TemperatureMonitor.html
    "Try Disk Utility
    1. Insert the Tiger Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
    The usual reason why updates fail or mess things up, or things don't load/run, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
    Some people get away without Repairing Permissions for years, some for only days.
    If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
    If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.

    The combo update for Intel-based Macs...
    http://www.apple.com/support/downloads/macosx10411comboupdateintel.html
    Repair Permissions before & after re-install, then reboot again each time.
    If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

    Just be sure to select Preserve Users & Settings.
    I only use Software Update to see what is needed, then get them for real via...

    That way I can wait a week or so, check the forums for potential problems, and get Permissions & such in order before installing.

  • Internet Connectivity Issues, 511 CPU Fan not detected

    Hello,
    I have been experiencing some issues with my HP ENVY Pohenix 800-060 (running Windows 8.1) PC lately.
    My internet connectivity has been acting crazy. Pages won't load fully. For example, when I am on Facebook I can't scroll down and have more posts load. I have to hit refresh and sometimes it will let me scroll down further than before. To load sites sometimes I have to hit refresh. If I am using just the wifi I am constantly connecting and disconnecting at totally random intervals but it's stable if I use an ethernet cable (however the other issues still persist). Images won't load fully as seen here
    Also, starting yesterday when I restart my computer I get an error message that says 511 CPU fan not detected. I have opened my computer and dusted the fan and I have also unplugged it and plugged it back in to the motherboard to make sure it's securely connected. What's strange is that this only happens about 8 out of 10 times when I start my computer, and if it does happen I can simply touch the fan to get it started and it will work just fine until I turn my computer off.
    I noticed in the HP Support Assistant that if you update to Windows 8.1 it says that you may experience internet connectivity loss and hardware problems so I don't know if these problems are related or not. I have checked and my drivers are up to date according to the HP website that searches for updates for you.
    I am currently backing up my computer and plan on resetting it to factory default if I can't find the source of these problems. 

    Eldrscrolls, welcome to the forum.
    Please check the CPU fan thoroughly before using the computer futher.  If it has failed you could fry the components.  I don't know if it has liquid cooling, but if so, be extremely careful.
    A System Recovery is a very good idea.  After updating Win 8.0 to 8.1 on my HP Split, I had several problems, such as, wireless connectivity.  I did the Recovery back to Win 8.0.  It solved my problems.  After a few days I gave Win 8.1 another chance.  It has performed admirably.  If the system is overheating because the CPU fan failed this could cause your problems, also.
